A page fault occurs when a program attempts to access data or code that is in its address space
but is not currently in the system RAM. So when page fault occurs then following sequence of events happens:

1. Check the location of the referenced page in the PMT

2. If a page fault occurred, call on the operating system to fix it

3. Using the frame replacement algorithm, find the frame location 4. Read the data from disk to memory

5. Update the page map table for the process

6. The instruction that caused the page fault is restarted when the process resumes execution.
